ISRO saved Chandrayaan-2 from colliding with KPLO, South Korea's first lunar orbiter, by altering its orbit manoeuvre which was scheduled to be executed on September 19, according to an unclassified report. The orbiters' possible collision was estimated to take place on October 1. ISRO said it altered Chandrayaan-2's next manoeuvre too to avoid "post-manoeuvre conjunctions with other orbiters".
